Keeper for locks



Oct, 29, 1935. R. GRILL KEEPER FOR LOCKS Filed April 17. 1935 INVENTORfludol Grz/ll ATTORNEY WITNESSES mfim Patented Oct. 29, 1935 UNITEDSTATES PATENT oFFIcE 3 Claims.

This invention relates to keepers for locks, latches, and the like, anobject being to provide an improved construction whereby the keeper maybe readily adjusted toward and from the object to which it is secured soas to take care of the bolt or latch member of the lock.

Another object of the invention is to provide an improved constructionof keeper for locks, wherein the head is not only adjustable through theaction of the threaded structure, but through the use of liners orspacing washers, whereby pressure brought to bear on the'keeper will notinjure the threads used in holding the parts together.

An additional object, more specifically, is to provide a keeper forlocks whereby the handle of the lock may be used as a lever against thehead of the keeper for prying the door open, the structure being suchthat this pressure will not injure any part.

This application is a continuation in part of my Patent No. 2,007,854,issued July 9, 1935.

In the accompanying drawing Figure 1 is a longitudinal verticalsectional view through part of a refrigerator showing the lock inelevation and a keeper embodying the invention in section;

Fig. 2 is an enlarged fragmentary sectional view through the keepershown in Fig. 1, but with the various parts shown slightly spaced apartfor the purpose of illustration;

Fig. 3 is a view similar to Fig. 2 but taken at right angles thereto inorder to show the protecting flanges or side walls;

Fig. 4 is a top plan view of one of the liners or spacing washers shownin Fig. 3;

Fig. 5 is an enlarged fragmentary sectional view illustrating how thewashers interlock and are thereby prevented from any turning action.

Referring to the accompanying drawing by numerals, l indicates the wallof a refrigerator, and 2 the door to which a lock 3 is connected. Itwill be understood, however, that the keeper embodying the inventioncould be associated r with other devices than refrigerators, but asshown in Fig. 1, the keeper 4 and the lock 3 have been connected with arefrigerator. The lock 4 is provided with a handle 5, pivotally mountedat 6. The handle 5 is provided with an extension I which may besufiiciently long to press against the keeper 4, if desired, wherebywhen the handle 5 is swung over to the correct position, the bolt 8 willbe withdrawn and the extension I will press against the keeper 4 so asto pry the door 2 open. The extension I and the bolt 8 both coact withthe keeper, the keeper acting to hold the bolt against being tamperedwith by any one attempting to force the same to a retracted position.

The keeper 4 is provided with a base 9 hav- 5 ing one or more aperturesIII for receiving retaining screws, and also a hidden aperture I I forreceiving a retaining screw which cannot be removed until after the headI2 has been removed. The head I2 is' provided with a rounded surface 10I3 against which the extension I is adapted to press, and with athreaded shank I I having a flattened portion I5 for receiving a lockingset screw I6. When the shank I4 is screwed in the desired distance theset screw I6 may be tight- 15 ened and the head I2 will then remain inthat place. However, where the extension I of the lock 3 is used orwhere the head is liable to be hit, it is desired to provide washers I'Iso that the strain from the blow will be distributed 20 through washersto the base 9 rather than to the threads of shanks I4 though the threadsi11 tak up some of the strain. Preferably the parts are so positionedthat the shanks I I will screw down to such an extent that the lowersurface of head I2 will press tightly against the washer II, wherebywhen pressure is applied to the head I2 it will relieve the tension onthe threads rather than produce a tension thereon. In order to preventthe rotation of the washers II which are of the same general shape asthe head I2, these washers are provided with pressed-up portions I8which interlock as shown in Fig. 5, the pressedup portion I8 fits into adepression I9 in the base 9. In addition, the base 9 is provided with apair of flanges or wings 20 and 2| which prevent access to the screw I6,or to the inner end of the bolt 8, so that an unauthorized person cannotpass an instrument into a position in front of the bolt 8 and crowd thesame to a retracted position. When a screw 22 is placed in position, thebase 9 cannot be removed without removing the head I2 even though theother screws are removed, and as the bolt 8 extends into what may betermed a chamber 23, the keeper cannot be rotated. It will be understoodthat the keeper 4 may be used with a lock similar to the lock 3 or withlocks of other kinds provided with bolts adapted to be projected intothe chamber 23.

I claim:

1. A lock keeper including a base having a threaded bore, a keeper headhaving a threaded shank adapted to be screwed into said bore, aplurality of interlocking washers adapted to inthereof, and means forlocking said keeper head against rotation.

3. A lock keeper including a base having a threaded bore and a pair offlanges coacting with the base to produce a bolt-receiving chamber, anda keeper head having a shank adapted to be screwed into said threadedbore with a portion overlapping said chamber and forming a covertherefor so that said chamber will be open only on one side. 10
